REFramework has a plugin that disables sharpening, but that also breaks TAA. There are hex edits for non-RT builds of RE2 & 3, but not updates (at least I haven't found them). Plus, having this as a mod option would be more convenient and wouldn't require editing the .exe every time you download the game.
This would be something to look into for reframework itself. It wouldn't make sense for me to add this feature to my mod when it's already mostly implemented in REFramework.
